Right now im on dbol test enth and deca, the deca is 300mg ml and as this is my first injection of this concentration so i dont know if its normal that right after i puled out the syringe it starting hurting like hell kinda like a stinging feeling, this is the third day and it still hurts alot,it is not swollen but it is a little red,i think the redness is just irritatation, i feel great and have no other problems,but could it be because its highly concentrated?
